I don't think this is a great metric of literacy. For one not all books are exactly high quality, and now more than ever there's a plethora of non-book written content available to us.
I used to read a lot of books when I was in school but these days I rarely do, however I probably consume more written word than ever. News, blogs, documentation, various and sundry articles. I read a lot, just not books anymore.
All this to say, I don’t understand “number of books read” as a metric of smartness or literacy or intelligence. Maybe it is easier to survey this metric and collect data? Sounds lazy research to me.
When it comes to getting an advantage, people often look the other way at meanness.
For example, it’s easy to complain about how Amazon treats their employees. Yet, we choose to buy from Amazon because it’s convenient, cheap, and everyone else is doing it.
We might see an organization treat someone else unfairly but when resources are scarce, we often look the other way because it feels like there is nothing one person can do.
I like the old black and white movie, The Invisible Man, to demonstrate the situation of a specific type of meanness that seems ever present today. The enemy is invisible and is only defeated when the entire community gets involved.
This isn’t complaining, just pointing out the reality - we actually don’t have as many options as we think we do. If one has extra money, they can spend a little more and shop at smaller but expensive places, most people are going to shop at Walmart or Amazon
